removeAttribute() method not found on array

I've added a fix based on some other issues also reported to the PR over on GitHub (https://github.com/emulsify-ds/emulsify_twig/pull/61) that should address these three Drupal.org issues:

https://www.drupal.org/project/emulsify_twig/issues/3160391 🐛 Check if 'attributes' index is set in bem context Needs review
https://www.drupal.org/project/emulsify_twig/issues/3210140 🐛 Error offsetExists() when i use 'twig_render_template' function Needs work
https://www.drupal.org/project/emulsify_twig/issues/3302662 🐛 PHP error on passing array in attributes variable with add_attributes() Needs work

If someone can review it and let me know if that works, I'll merge that in. Thanks!

This has now been fixed in version 5.0.0. Thank you!
